+# Loop Over A List Of Dictionaries
+
+Ansible's `loop` can iterate over a list of dictionaries in a task. That task
+will be evaluated for each `item` in that list. Since each `item` is a
+dictonary, we can access the fields on the `item` directory with dot notation —
+`item.name`.
+
+Here is what this would look like for a task that is setting up authorized SSH
+keys.
+
+```yaml
+---
+- hosts: all
+  vars:
+    dev_users:
+      - name: alice
+        ssh_key_url: https://github.com/dev1.keys
+      - name: bob
+        ssh_key_url: https://github.com/dev2.keys
+  tasks:
+    - name: Set authorized keys taken from url
+      ansible.posix.authorized_key:
+        user: "{{ item.name }}"
+        state: present
+        key: "{{ item.ssh_key_url }}"
+      loop: "{{ dev_users }}"
+```
+
+Notice the `loop` over the `dev_users` variable gives us access to an `item` in
+the task. Because each `item` has a `name` and an `ssh_key_url`, we can access
+those fields in the task.
